LINUS TECH TIPS STORAGE RANKING SCRIPT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ DESCRIPTION ──────────────────────────────────────────────────────────── Generates a text file with the BB code for the forum post as well as graph images for statistics. Uploads graph images to a server automatically if one is specified. DEPENDENCIES ──────────────────────────────────────────────────────────── JSON::XS File::Spec Time::Piece Digest::SHA1 List::Util Data::Dumper Net::FTP GD GD::Text GD::Graph USAGE ──────────────────────────────────────────────────────────── • Download all necessary files and directories: ltt-rankings.pl fonts/ images/ json/ Ltt/ • Enter the correct system information into the json/systems.json file. ┌─────────────────────┐ ┌───┤ json/systems.json ├────────────────────────────┐ │ └─────────────────────┘ │ │ │ │ ... previous entry ... │ │}, │ │"system_XXX" : { │ │ "capacity" : "XX.X", │ │ "case" : "Case Model", │ │ "hdds" : { │ │ "AAXXXX" : "X", │ │ "BBXYXX" : "Y", │ │ "CCXQXX" : "Z", │ │ "AAXXVX" : "N" │ │ }, │ │ "notes" : null, │ │ "post" : "post number", │ │ "os" : "Operating System", │ │ "storage_sys" : "Storage System Abbreviation", │ │ "username" : "Username on Forum" │ │} │ │ │ └──────────────────────────────────────────────────────┘ NOTES: ◦ The order in which the entries (case, hdds, ...) appear is not relevant. ◦ The notes field may or may not be set. If it is set, it will be pasted as-is into the post text, so if you wish to use BB formatting for that, just enter it like you would into the forum post. ◦ The HDD descriptors must be present in the json/hdd_types.json file. See below for an explanation on HDD descriptors. ◦ Technically speaking, the capacity field is optional at the moment, but for historical purposes or potential future use we will continue to use it for now. ◦ See below for a list of abbreviations for the storage_sys and os fields. ◦ Make sure to follow JSON syntax: - double quotes, - no commas for last entry in a given data structure. • Create a credentials file json/credentials.json of the following form: ┌──────────────────────────┐ ┌───┤ json/credentials.json ├───────────────────────┐ │ └──────────────────────────┘ │ │ │ │{ │ │ "ftp_user" : "YOUR_FTP_USERNAME", │ │ "ftp_pass" : "PASSWORD", │ │ "ftp_server" : "FTP_SERVER", │ │ "img_server" : "URL_WHERE_IMAGES_WILL_BE" │ │} │ │ │ └──────────────────────────────────────────────────────┘ Alternatively, one can omit the credentials file, in which case the graph images will be merely stored in the images/ directory, but will not be uploaded to a server automatically. • Run ltt-rankings.pl. • The output files will be: ◦ ltt-rankings.txt: The text for the forum post. ◦ images/*.png: The image files for the statistics plots. • Open forum editor, switch to rich text mode (not raw BB code editing mode). This is necessary because if the text is inserted in raw mode, the padding spaces for the post formatting will be stripped away when the post ist posted. When posting in rich text mode, the padding spaces are preserved. Copy and paste text from ltt-rankings.txt into forum editor, save post and done. ABBREVIATIONS ──────────────────────────────────────────────────────────── Abbreviations as defined by the abbreviations_key field in json/constants.json: WS Windows Server WHS Windows Home Server SHR Synology Hybrid RAID StSp Storage Spaces RD RAID (unspecified if hardware or software) HwRD Hardware RAID SwRD Software RAID FlRD FlexRAID When more abbreviations are introduced, make sure to enter them into the abbreviations_key field in the json/constants.json file. HDD DESCRIPTORS ──────────────────────────────────────────────────────────── HDDs are classified by vendor and size, not by model. The scheme for the HDD descriptor is: AAXXXX Where "AA" is a two-letter code for the manufacturer as defined below, and "XXXX" is a four-digit code for the HDD size. The vendor codes are: HT Hitachi SG Seagate SS Samsung TS Toshiba US unspecified vendor WD Western Digital Company The size descriptor is four digits describing ten gigabytes, so it would look like this for example: 3 TB disk 0300 500 GB disk 0050 1.5 TB disk 0150 and so on. So a Hitachi drive of 2 TB capacity would have the HDD descriptor of: HT0200 If an HDD descriptor is used in json/systems.json which does not occur in json/hdd_types.json, the scrip will throw a fatal error and die, notifying the user to amend the records appropriately.
